hydronium

 [hi-dro´ne-um]
the hydrated proton H3O+; it is the form in which the proton (hydrogen ion, H+) exists in aqueous solution, a combination of H+ and H2O.

hy·dro·ni·um ion

the hydrated proton, H3O+, a form in which hydrogen ion exists in aqueous solutions; also, H3O+·H2O, H3O+·2H2O, etc.
Synonym(s): oxonium ion

Moreover, certain quantum mechanical effects that influence a hydroxide ion's movement have significantly less effect on a hydronium ion in water, says Tuckerman.
The decrease in lead uptake by acid desorbent might be due to the increase of the concentrations of competing hydronium ions.
At lower pH (acidic pH), the adsorbent surface will be completely covered with hydronium ions which compete strongly with metal ions for adsorption sites.
In the second, a water molecule picks up a proton, creating a hydronium ion (H3O+).
4) the transition elements are eluted to the detector via nitric acid; during this process, the resin is converted to the hydronium ion form;
1) Environmental factors: The main causes affecting the engineering of concrete containing S0 ~ 4-, Mg and ~, CI, Ca 2+ hydronium concentration, reaction zones, and the dissolution of the freezing cycle and alternately dry and wet conditions and had eight aspects.
The hydronium ions can penetrate the cellulose chains in these amorphous domains promoting the hydrolytic cleavage of the glycosidic bonds and finally releasing individual crystallites.
In case of clay micas (illites) the interlayer space is partly occupied by hydronium ions [([H.
It bears repeating that pH is the negative logarithm (base 10) of the hydronium ion ([H.
Alunite, natroalunite, jarosite, natrojarosite and perhaps some hydronium jarosite are all present at Mazarron, and the silver content in these minerals is less than 0.
Moreover, hydronium ion has an influence on the chromium rejection because of its adsorbent capacity and effects on the chemical nature of the metal ion.
Hydronium jarosite is probably also present, and perhaps even argentojarosite (thought by mining engineers to be the main ore mineral at a new operation on the east slope).
